Detecting proper bison version before make

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I just installed Postgres on an older machine and was surprised
that configure did not throw an error about running an old version
of bison, but let me get a bit into the whole 'make' cycle before
a cryptic error was thrown. Can the configure script be made to check
for a proper version of bison?
